Title: Improvements in or relating to pressurized liquid dispensing containers
IPC: A47K5/14
Filed: 1960-12-02
Abstract: 973,342. Dispensing liquids by gaseous pressure. GILLETTE CO. Dec. 2, 1960 [Dec. 9, 1959], No. 41524/60. Heading FIR. An aerosol container for dispensing heated quantities of a liquid, e.g. a foam-type shaving cream, comprises a chamber 12 of sheet metal mounted in the neck of a conventional container 10 and heatable, for example, by the external application of hot water or air. When a discharge valve 23 is opened by depressing or tilting a member 25, aerosol liquid from container 10 enters chamber 12 via a dip tube 15 and a baffle plate 16 and displaces the heated contents of the chamber through a nozzle 26. To improve heat distribution, chamber 12 is partially filled with metallic wool 27 and may also be provided with external or internal fins. Several alternative baffle constructions may be employed to direct the incoming flow of aerosol on to the heated walls of chamber 12.

Title: Filter Signal Device
IPC: A47L9/19
Filed: 1966-09-16
Abstract: 1,153,465. Suction cleaners. NATIONAL UNION ELECTRIC CORP. 16 Sept., 1966 [21 Oct., 1965], No. 41569/66. Heading A4F. [Also in Division B1] A vacuum cleaner (Fig. 1, not shown) comprises a clogging indicator which responds to rising differential pressure between the inside of the casing, upstream of the fan, and the atmosphere to give a variable visual signal, followed by an audible signal when the filter is further clogged, accompanied by a sufficient intake of air to keep the fan motor cool if the signals are ignored. In Fig. 4 the indicator is mounted in the roof of the cleaner casing and comprises a piston 62 loosely slidable in a bore 60 of a transparent housing. The lefthand end of bore 60 is circular in cross-section, the right hand end is vertically elongated to accommodate two channels (68) (Figs. 3, 5, not shown) which open into the casing between a paper filter bag (41) and fan-motor unit (30). Air continuously bleeds into the housing through passages 97, 112, 83, 82, round the loose piston 62 and out by channels 68. Thus the piston is urged rightwards by the pressure of the air bleed, against the action of spring 72 and the pressure within the cleaner casing acting on the hollow interior of the piston. The lower wall of the housing is covered by reflective or fluorescent material 101 which is exposed to view through a window 100 as piston 62 is moved progressively rightwards (from its position in dotted lines) by the clogging of the filter bag. When the piston clears the end of passage 82 (as shown in full lines) the air bleed increases substantially, causing a reed 102 in passage 112 to vibrate and raising the air flow through the. fanmotor unit sufficiently to keep the motor cool with the filter bag fully clogged. In Figs. 7 to 11 (not shown), there is direct passage for bleed air to the left hand end of piston (134), which slides on an internal support (143), and the reed is dispensed with an audible signal being generated by air flow through aligned apertures (126, 156) into the bore when the piston is withdrawn.

Title: An improved rotary sliding vane internal combustion engine
IPC: F01C1/344
Filed: 1962-11-05
Abstract: 1,003,607. Rotary sliding vane internal combustion engines. F. E. HEYDRICH. Nov. 5, 1962 [Jan. 31, 1962], No. 41743/62. Heading F1F. A rotary sliding vane I.C. engine comprises a rotor drum 1, Fig. I, having end flanges 2, 3 formed with radial slots 19 in alignment with axially extending rotor slots in which the vanes 7, Fig. III, slide, to support the vanes, and so reduce the tendency to tilt and jam and also reduce bending stresses thereon. Combustion mixture is supplied to the engine through a rotor bore 6 whence it passes by way of holes 11, Fig. II, and radial holes 5 in the end flange 2 to a manifold chamber 12 before entering the engine working chamber through ports 14, 15. The charge cools the rotor and in passing through the holes 5 receives an initial compression. The charge which on clockwise rotation of the rotor passes into an intake zone A, is compressed in zone B and ignited by flash-back of gases from a previous combustion passing through apertures 33 and a chamber 32 as a vane passes between the apertures. This reduces any tendency in the development of "hot-spots" or oiling up of ignition. Ignition is initially by means of a spark-plug or glowplug screwed into the chamber 32. No timing is necessary so that a continuous spark from an oscillator or trembler coil may be used or in the case of the glow-plug an electric current from any source. Air passing through holes 22 in the outer casing 23, passes through cooling and impeller vanes 8 on the end flange 3 and is directed through ducts between the outer casing and the stator before exhausting to the atmosphere. Lubricant is added to the charge to lubricate the rubbing surfaces between the vanes and the inner periphery of the stator. The rotor bearings may be lubricated by molybdenum disulphide greases or by drip or pressure feed. In large engines the end flanges may extend beyond the rotor drum to give added support to the vanes. To reduce weight, the vanes are preferably made from a pair of vane members, Fig. VIIa, urged apart by resilient means. Cam rollers mounted on shafts passing through slots in the end flanges 2, 3 may be fitted to limit the radial movement of the vanes 7 so that they never actually contact the inner periphery of the stator and so reduce wear. The vanes may be interconnected by levers or by small pistons operable in suitable bores to achieve controlled vane movement. Suitable material combinations of rubbing parts to reduce wear are molybdenum alloy steels with cast iron and high carbon steels with nodular iron. Certain metal-plastic combinations and alumium alloys have also been found suitable.
